The bsltoh(), bcleartoh(), bsltoh_r(), bcleartoh_r(), h_alloc(), and h_free() functions are Obsolete. Use
the label_to_str(3TSOL) function instead.

The bsltoh() and bcleartoh() functions share the same statically allocated string storage.
They are not MT-Safe. Subsequent calls to any of these functions will
overwrite that string with the newly translated string. The bsltoh_r() and bcleartoh_r()
functions should be used in multithreaded applications.
